As to the OEMs, Soon is the key word here.
This doesn't mean after July 29; it means soon, probably mid-July.Soon, we will give a build of Windows 10 to our OEM partners so they can start imaging new devices with Windows 10. The new devices our partners are working on are very exciting, I can’t wait to hear your feedback as you get a chance to use them.
After that comes the media to retailers:
Soon after, we will distribute a build of Windows 10 to retailers all over the world, so they can assist their customers with upgrades of newly purchased devices that were originally imaged with Windows 8.1. Look for this sticker for assurance that our OEM partners have proactively tested a device for compatibility with Windows 10.
From this, it looks as if even the "brand new" stuff will have been tested and found compatible . . . The main thing that may turn up will probably be printers. I know HP is notorious for not building new drivers; however, my HP Officejet 7610 (very wide bed) installed beautifully as a wireless printer! I would have had to stay with a version of Windows 8.1 if it hadn't!With all of our ecosystem partners, we have been actively engaged to work on device and application compatibility. It’s been amazing to see the teamwork taking place across companies to ensure a quality experience as our shared customers experience Windows 10 soon. In our testing of millions of systems, we’re seeing full compatibility today with the vast majority of Windows 8x and Windows 7x systems– and we are not yet done, we will never be done – we will be continuing this application and device compatibility work every day as part of our ongoing commitment to Windows as a service.
I've not started 10 today, I got 100159 on Wednesday and was in 10 all day yesterday but still in 8.1 today, I run 10 in a VM.
I'll probably see about the new build tomorrow. I know I wasn't happy last thing yesterday, I usually go to Facebook and have a game of Bubble Witch Saga and Candy Crush Soda before shutting down for the night but last night it was so slow trying to click on a button and moving about I got fed up and shut it down and played in 8.1.
For me, the RTM version is just another build. What we have right now is the same OS that we will get on July 29 with some tweaking. Just enjoy what we have and don't get too excited. It will come when it comes. I will stay on Insider program as long as it is running.
The difference between RTM and GA is to give the computer builders (OEMs) a head start so they will have computers to sell to us on July 29. Put another way, RTM is the final build and is ready for everyone. GA is when commercial entities are allowed to sell their product.
So, on July 29, both new computers wearing Windows 10 will be for sale, as will DVDs and possibly flash drives with Windows 10 installation media on them. And, of course, a billion upgrades will start to happen.
